"Allen Ivanov, the 19-year-old arrested and jailed in the slaying of three people at a Mukilteo house party, was something of a high-tech wiz.

He was a computer science student who help to start his own company before he could drive. And he worked at a job in which he helped to unlock the digital mysteries of Apple phones and computer for its customers.

Still, his experience in the digital world of Twitter was brief and cryptic.

"First and last tweet. I've been through it all," he tweeted on Thursday.

A second tweet that day read: "What's Ruger gonna think?"

It's not clear that the reference to Ruger meant the firearms company.

Perhaps most disturbing is his Instagram post on Monday, July 25, 2016, that shows a rifle on the ground and three cartridges beside it. Included is a sticker from Supreme 16, a New York streetwear brand. The name "Christopher" is written on blue tape. It is his middle name.

"You can't run with me," he wrote as a caption.

By Saturday afternoon, people were adding angry and often obscene comments to his photos.

A game company he helped to found four years ago, Skirmos, describes itself as an open-source laser tag system. A Kickstarter campaign to fund it has raised almost $100,000. Part of the company's website that lists its team was removed Saturday.

Invanov is a student at the University of Washington at Bothell, where is studying computer science, according to his LinkedIn page. He graduated from Mukilteo's Kamiak High School in 2015. Among other things, he took part in chess and robotics at the high school.

Saturday night, families of the shooting victims were expected to gather at Kamiak High for a vigil.

He has worked at the Genius Bar at an Apple store for 10 months, helping customers with technical advice with their news digital devices. Before that was a sales clerk for Abercrombie & Fitch. He also delivered his local newspaper, the Mukilteo Beacon, for six years.

He speaks Russian as well as English, according to his LinkedIn page.

His family lives in a pleasant neighborhood in Mukilteo, where neighbors say they are a nice family who tend to keep to themselves.

One of his Instgram photos show a large suburban house with a sports car in front. "Family came from the gutter," is his caption.

On Saturday, he was booked into the Snohomish County Jail for investigation of first-degree murder and aggravated first-degree murder."

Any of you fuckers deal with Russian immigrants? The USA does not need filth such as them.
